Silage leachate and runoff can be extremely damaging to the walls and bases of concrete silage pits and clamps. It reacts with the chemicals in the concrete and erodes away the surface, exposing new concrete. The cycle then repeats, attacking the newly exposed concrete, breaking up the surface particles and washing them away to expose more and more. In order to prevent chemical attack from the leachate, the concrete can be covered with a protective coating. The type of coating will depend upon a number of factors:
REPAIRING SILAGE PIT / CLAMP CONCRETE BASES & BUND WALLS
The appropriate concrete repair material will depend upon the nature of the damage. The width and depth of cracks. A thin surface repair. The depth of any pothole. Our products are optimised to repair specific types and dimensions of damage.
It is always important to investigate and address the cause of any damage as well as making repairs. Full depth cracks through a base slab can be caused by ground movement, an insufficiently depth of well compacted hardcore base below the slab, too little reinforcement, an insufficient slab thickness, or other major structural issues. If the root cause of the problem isn't investigated and addressed, repairing a crack will not prevent the slab from cracking elsewhere. Cracks in the walls may also indicate ground movement or insufficient thickness of the walls to retain the tank of sillage when full.
Once any underlying structural issues are addressed and stabilised, repairs to cracks and patch repairs can be carried out.
Of course, given the aggressive chemicals produced during the silage process, the repair materials must be capable of withstanding the maximum concentration of chemicals expected – this will include if aerobic digestion is unintentionally allowed instead of anaerobic.
We can supply fast-track repair materials with high early strength gain and quick curing times, which are ideal if you only have a small window of opportunity to carryout repairs.
